FAM219B

Across TCGA pan-cancer cohorts, FAM219B Mutation is linked to patient survival in 2 of 34 cancer types, making it a survival-associated FAM219B data layer compared with 24 for mass-spec protein and 2 for mass-spec protein.

The strongest signal is observed in lung squamous cell carcinoma (LUSC), where higher FAM219B Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated FAM219B expression acts as an unfavorable survival marker.

LUSC and SKCM are the cancer types where FAM219B Mutation most reproducibly stratifies survival.

Mutation survival associations by lineage

Ranked by sampling consensus. AUC1 and AUC2 indicate survival in the high- and low-expression groups, respectively; the lower AUC marks the poorer-surviving group. p-values are from the log-rank test.
